Online AI video enhancer for frame-by-frame video quality upgrade
AI enhance video online — double resolution to 4K instantly
Double your video resolution with AI video enhancer that predicts and reconstructs real detail — not stretched pixels. 480p → 960p, 540p → Full HD 1080p, 720p → 1440p, 1080p → 4K Ultra HD. Sharper text, cleaner edges, and natural skin / sky / foliage textures.
Reduce noise & recover lost details — frame by frame
Every time a video moves through WhatsApp, TikTok, Instagram, or YouTube compression, detail gets stripped — colors flatten, edges blur, grain creeps in. UniFab's AI video enhancer reverses the damage by analyzing patterns across consecutive frames, reconstructing lost textures, and reducing noise intelligently. The result: clear, natural-looking video quality without the artificial "AI sheen" of single-pass tools.

Yes. UniFab Online supports 2x AI upscaling — if your source video is 1080p, the output is 4K (2160p). For lower-resolution sources (480p → 960p, 540p → 1080p, 720p → 1440p), or for higher upscaling like 4x to 8K / 16K with all AI models, try the UniFab Desktop app with local GPU acceleration.
UniFab's AI video enhancer fixes a wide range of video quality issues: blurry or out-of-focus footage, low resolution, compression artifacts from WhatsApp / TikTok / Instagram / YouTube, video noise and grain, poor lighting, and color imbalance. It works especially well on old family videos, screen recordings, gameplay clips, and downloaded social media videos.
No. UniFab's AI video enhancer is tuned to enhance naturally — it reconstructs real detail rather than over-sharpening or applying heavy filters. The result preserves the original look of your footage without the artificial "plastic" or "AI sheen" appearance common with single-pass enhancers.
